Introduces the 'gp_random_insert_segments' GUC to reduce the generation of excessive fragmented files during the insertion of small amounts of data into clusters with a large number of segments (e.g., 1000 records into 100 segments).
Fragmented data insertion can significantly degrade performance, especially when using append-optimized or cloud-based storage. By introducing the 'gp_random_insert_segments' GUC, users can limit the number of segments used for data insertion in randomly distributed tables, which can significantly reduce fragmented files.
